The placement of Speed Clamps for ROLAND 200

Remove the old clamps along with their retainer parts and springs. At the rear side of the cylinder cavity, in the groove, sketch A, there is a steel blade and 4 small cylinders. This steel blade and the 4 small cylinders have to be removed because they are no longer required. The other steel blade that is at the front side of the cylinder cavity has to remain in its position after cleaning it because it is required. Clean the whole cylinder cavity well and particularly the groove of the rear side, where you removed the steel blade and the 4 small cylinders. Check the front clamp if the two register pins N17 & N19 are at their correct sides depending on what kind of punch machine for the plate you use because there is a difference of 1mm in the depth of cutting the plate between the various punch machines. If the register pins need to be changed, you have to loosen the screws (fig.9) that hold them. You remove them and you reinstall them on their opposite sides. The difference between the two sides of pins is shown in sketches B and C. If you use plates with no holes then you remove the two register pins. If in future you use plates with holes, you reinstall them very easily. Spread a fine film of grease on the faces of the retainer parts of the clamps and on the face of the steel blade for the fast and parallel shifting mechanism E37 for the rear clamp. Place the clamps in their positions in the cylinder cavity as they are connected by “the mechanism for placing and removing safely” N68 secured with pins (fig.11). The springs R0 are now compressed and the three retainer parts E24/E23/E24 are in their place.

As they are connected, place and screw completely the three screws of each side-end retainer part E24 of clamps. With the help of the two aluminum wrenches, first of all remove the pins (fig.11) that keep the clamps connected and the springs are released. Then, place the front screw (fig.2) into the middle retainer part E23 without tightening it. Unscrew the four operating screws of the rear clamp E35 completely (about 4mm) in order to shift the rear clamp forwards. By the double adjusting screw H18 move the two parts of the split rear clamp to enlarge the margin between them so as to leave space in order to place and tighten the middle and back screws of the middle retainer part E23. After that, turn reversely the double adjusting screw H18 to bring the two pieces of the split rear clamp in the correct margin. With the help of the aluminum wrench, remove the front clamp so as to leave space in order to tighten the front screw of the middle retainer part E23 (fig.2) completely. Restore the 4 operating screws E35 of the rear clamp into their initial position. The new speed clamps are now in place.

THE OPERATION OF SPEED CLAMPS

The upper clamp opens and closes with the lever wrench N41. In order to close the clamp, you have to move it forwards to the lid end (fig.8). For the opening of the clamp, the lever wrench has to be moved backwards until you feel that it has fallen into a flat gap. The upper and lower parts of the clamps are connected together with a series of Hexagon socket countersunk head screws N04-M8X30 that are for adjusting, when required, the pressure that holds the plate. The adjustment is always regulated with the plate tightened. For the above adjustment, you must use a long hexagon socket key 6mm by moving it only a little. You have to use some strength because the above screws are secured with a plastic ring N51/N56. There are compression springs N08 between the two parts of the clamp that help to open the upper part (lid).

-In order to place the new plate you have to do the following:

FRONT CLAMP: The end adjusting screws H19 must not push the clamp right or left so that the self-centering mechanism E09/F10/E11 can keep the clamp automatically in the center. If during the set-up you use the end adjusting screws to move the clamp right or left, keep these screws tightened till the end of the particular work. By the two operating side screws E25 place the clamp in position “O”. In this position, the horizontal line (fig.4) of the ring scale N30 is aligned with the face of the clamp and the bold vertical line is on the top. If later the indicator needs correction, there are two small screws (fig.7) that will put it in the right place. You can also place the clamp in position “O” by using the two special adjusting screws E27.

These screws are not for the stretching of the plate, if you use them, they always remain in the same position where you have adjusted them. Unscrewing the 4 operating screws E25/E26, the clamp by these two screws remains in the standard position “O If during the set up you need to move the clamp forward, unscrew the adjusting screws E27 and after the printing process place them back to their correct positions with the help of the ring’s line. If they are not useful, unscrew them a few mm and they are as they do not really exist there. (These operating screws are secured with a plastic ring to turn hard). For the above adjustment, you can also use the two indicator sets N32 so as the middle thick line (fig.6) to be aligned with the face of the clamp.

REAR CLAMP: At first, use the special toothed screw (red) N60, which you turn left, to move the clamp toward the side of the cylinder. Place the 4 operating rear clamp screws E35 in position “O”. In this position, the horizontal middle line (fig.5) of the screw’s ring is aligned with the face of the clamp. Bring the two pieces of the rear clamp in the center by using either the end screws H19 or by pushing the clamp. Align the two parts of the split rear clamp with the groove (fig.10) of the middle retainer part E23 and correct the margin between them by using the double adjusting screw H18. Place the new plate as always. Remember to press the lever wrench N41 so that the clamp is closed and the lever wrench touches the upper part of the clamp (fig.8). It is better not to close the first part of the clamp to the end. It is preferable to close the second immediately and then go back to the first for the final closure. In this way the plate does not warp. After that, turn the special toothed screw (red) N60 of the mechanism, to the right, for fast shifting of the rear clamp.

ATTENTION: This special screw (red) N60 must be turned up to the end, until you feel that it has reached the end of its cycle.

SPECIAL ATTENTION MUST BE TAKEN IF IT IS DIFFICULT TO BE TURNED. IT IS NECESSARY TO UNSCREW LIGHTLY THE 4 OPERATING SCREWS E35 OF THE CLAMP FOR THE STRETCHING OF THE PLATE. THIS SPECIAL SCREW IS NOT FOR COMPLETELY STRETCHING THE PLATE. IT IS JUST FOR MOVING THE CLAMP IMMEDIATELY, WITHOUT USING MUCH FORCE. The function of the special screw (red) N60 has been completed. As mentioned above do not use this special screw for the final stretching of the plate or for the different adjustments on the clamps. Tighten the 4 operating rear clamp’s screws E35 completely and do the same at the front clamp’s operating screws E25/E26. From now on, the operation of the clamps for the final coincidence of the colors or for the corrections, is, as it was with the old clamps.
